2: "The Mapping Of Chromosome 16", Norman A. Doggett, Raymond L. Stallings, Carl E. Hildebrand, Robert K. Moyzis

Genomics: Past & Future

Human chromosome 16 is the main focus of the mapping efforts at Los Alamos. The large photomicrograph on these opening pages illustrates the starting point for those mapping efforts, the evaluation of our chromosome-16-specific library of cloned fragments. Among the 23 pairs of human chromosomes, one pair, chromosome 16, is identified by fluorescence in-situ hybridization. Thousands of yellow fluorescent probes derived from the clone library have hybridized to both copies of chromosome 16. The high density and uniform coverage of the fluorescent signals were a strong indication that we could use the library to construct a map of overlapping cloned …

G92-1071 Ridge Plant Systems: Weed Control, Robert N. Klein, Gail A. Wicks, Alex Martin, Russell S. Moomaw, Fred Roeth, Robert G. Wilson, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

Advantages and disadvantages of the ridge plant system, weed control before and at planting and economics of the system are discussed. Ridge planting combines tillage and herbicides to achieve improved weed control in row crops. Crop seed is planted into ridges formed during cultivation and/or ditching of the previous crop. In ridge planting, the planter follows the old row and ridge clearing sweeps or disks move the surface soil, residue and much of the weed seed out of the row. Weed seeds are deposited between the rows where, upon germination, they can be controlled with cultivation. Two cultivations are generally …

G92-1115 Corn Quality For Industrial Uses, David S. Jackson

University of Nebraska-Lincoln Extension: Historical Materials

Characteristics of corn used by industry are discussed here. Publications frequently refer to the term "Corn Quality," but this term means little without being placed in context. The Official U.S. Standards for Grain defines Corn Quality for typical marketing transactions involving grain marketed in the United States. It rates corn quality based on purity, color, the amount of broken and foreign material, total numbers of damaged kernels (including heat-damaged, sprouted, frosted, weather or ground damaged, moldy, diseased), heat-damaged kernels, stones, moisture, and test weight. Official standards, however, are only useful as general indicators of grain quality.

G92-1112 Lice Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Identifying and controlling lice on cattle both are covered here.

Cattle lice may be the most underestimated livestock insect in terms of economic losses. The USDA estimates that U.S. livestock producers lose $125 million a year to cattle lice.

Heavy louse populations cause lowered milk production, loss of flesh, stunted growth, general unthriftiness and anemia. "Chronic" or "carrier" cows may abort due to louse-induced anemia. During severe winters, louse-infested animals are more susceptible to respiratory diseases.

G92-1099 Estimating Effective Rainfall, Joel E. Cahoon, C. Dean Yonts, Steven R. Melvin

University of Nebraska-Lincoln Extension: Historical Materials

How irrigators can estimate effective rainfall, and use that estimate to schedule irrigations properly. Scheduling irrigation based on crop demand (see NebGuide G85-753 Irrigation Scheduling Using Crop Water Use Data, on the checkbook method) requires an estimate of effective precipitation or rainfall. Effective rainfall estimates are also important for planning cropping sequences in both dryland and irrigationd crop production. Effective rainfall is the amount of rainfall stored in the crop root zone. Rainfall that runs off the soil surface or passes through the root zone does not contribute to crop growth and yield. There are two steps to estimating effective …

Participation in the National Poultry Improvement Plan to prevent egg-transmitted diseases to small flocks, game birds, hobby, and exhibition flock owners is explained in this NebGuide.

The National Poultry Improvement Plan (NPIP) is a cooperative state/federal program that was established in 1935 to reduce and eventually eliminate several diseases transmitted primarily through infected breeder flocks and theirs eggs. The plan's widespread acceptance among the commercial industry has almost completely eliminated Salmonella pullorum and Salmonella gallinarum from commercial breeding stocks. Participation in the plan has saved the commercial industry and small flock owners millions of dollars due to improved health and …

G92-1096 Understand Your Soil Test: Ph-Excess Lime-Lime Needs, K.D. Frank, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

The relationships among pH, soil type, and lime requirements are explained.

Accurate soil tests can be an excellent management tool. Misuse of soil tests leads to increased production costs, yield losses, or both. The elements required by plants for proper growth have been determined by experimentation. Experience has shown that soils across Nebraska differ greatly in their capacity to supply these elements. The amount of each element supplied by a soil depends on several factors. Two important ones are: (1) the type of material from which the soil was formed, and (2) the treatment the soil has received since being …

Ec92-270 Conducting Pig Feed Trials On The Farm, Duane Reese, Walter W. Stroup

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this publication is to provide fundamental information that must be understood before attempting to conduct a feed trial. The concepts and procedures described here are valid for most situations involving a comparison of two feeds. Any trial involving more than two feeds raises issues that are beyond the scope of this publication. Those issues are covered in university statistics courses on design and analysis of experiments.

We suggest that pork producers adopt a "best cost" feeding program tailored to the operation and based on sound nutritional principles. Feed cost per pound of gain is a major item …

Ec92-125 On-Farm Trials For Farmers Using The Randomized Complete Block Design, Phil Rzewnicki

University of Nebraska-Lincoln Extension: Historical Materials

Farmers are interested in evaluating new agricultural practices on their own farms. To produce results credible to themselves, other farmers, and researchers, a systematic method of testing should be used. If a comparison of agricultural practices results in one practice yielding a few more bushels of crop than another, this does not necessarily mean it is a more valuable practice. The difference may simply be due to field variation or chance.

This circular discusses the on-farm trials and incorporation of the two basic requirements in designing experiments: randomization and replication.

G92-1119 Rust Diseases Of Turfgrass, John E. Watkins, Roch E. Gaussoin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the various rust diseases common to Nebraska and offers suggestions for maintaining a vigorous and disease-resistant lawn.

Rust diseases occur on all turfgrasses; however, most rust problems occur on Kentucky bluegrass, perennial ryegrass, tall fescue and zoysia. In the cool-temperate regions of North America, cool season turfgrasses may suffer severe injury late in summer by attack from one of the rust pathogens. In addition, rust-weakened plants are much more susceptible to injury from environmental stresses and to attack by other turfgrass pathogens.

G92-1080 Farmstead Safety Evaluation Guide, Gerald R. Bodman

University of Nebraska-Lincoln Extension: Historical Materials

Safe working conditions for personnel and safe, healthful living conditions for animals are critical requirements in the design of all farmsteads.

All farmsteads periodically should be evaluated for potential hazards and conditions that could lead to injury, death, or premature building failure or loss. Some hazards develop with time and are easily overlooked. Others are the result of poor planning or just being "too busy." To assess the safety of your farmstead and buildings, answer the following questions. Any question that cannot be answered with a firm "yes" indicates a need for corrective action.
